There was an article in Field and Stream a couple months back about a

Get a big striper & he'll tow you a ways out. Hope he's careful

The angler who was profiled in the article
is a strong swimmer and has been doing this quite a # of years. The
writer, otoh, only went out with him one night and once was enough LoL
